TECHNICAL FIELD

The present subject matter relates to drinking straws, and more particularly, to a foldable reusable drinking straw and a container therefor.

BACKGROUND

Over 500 million disposable plastic straws are used and thrown away each day in the United States. This results in excess plastic in trash dumps, and unfortunately, pollution in waterways and oceans. One solution to not using plastic straws is for people to carry their own, reusable straws. But one problem is that reusable straws are often made out of glass or metal, and by nature are long and inconvenient to carry around. Glass straws are easy to break and need a bulky case to keep them from snapping. If people are to bring reusable straws everywhere, they will want somewhere clean to put the reusable straw. That means keeping the reusable straw in a case that's even bigger and bulkier than the rigid glass and metal straws in their current form. Therefore, there exists a need for a convenient reusable drinking straw that is easy to carry, store, and easy to clean.

As explained above, reusable straws are known in the art, but while such straws according to the prior art provide a number of advantages, they nevertheless have certain limitations. The present disclosure seeks to overcome certain of those limitations and other drawbacks of the prior art, and to provide new features not heretofore available. A full discussion of the features and advantages of the present disclosure is deferred to the following detailed description, which proceeds with reference to the accompanying drawings.

DETAILED DESCRIPTION

While this disclosure is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail preferred embodiments with the understanding that the present disclosure is to be considered as an exemplification of the principles of the disclosure and is not intended to limit the broad aspect of the disclosure to the embodiments illustrated. It should be noted that the features illustrated in the drawings are not necessarily drawn to scale, and features of one embodiment may be employed with other embodiments as one of ordinary skill in the relevant art would recognize, even if not explicitly stated herein. Further, descriptions of well-known components and processing techniques may be omitted so as to not unnecessarily obscure the embodiments of the present disclosure. The examples used herein are intended merely to facilitate an understanding of ways in which the present disclosure may be practiced and to further enable those of ordinary skill in the art to practice the embodiments of the present disclosure. Accordingly, the examples and embodiments herein should not be construed as limiting the scope of the present disclosure, which is defined solely by the appended claims and applicable law.

Generally, this disclosure describes a foldable reusable drinking straw and a container for retaining the foldable reusable drinking straw in the folded state. Referring now to the figures, and initially to FIGS. 1-3B, there is shown a foldable reusable drinking straw 100. In one embodiment, the foldable reusable drinking straw 100 is flexible. In another embodiment, the foldable reusable drinking straw 100 is made of silicone.

In one embodiment, the drinking straw 100 comprises a tube 102 having a tubular wall structure 104 with an outer surface 106 and an inner surface 108. The inner surface 108 defines a bore 110 having an inner diameter. The tube 102 has a first end 112 and a second end 114. The bore 110 extends from the first end 112 of the tube 102 to the second end 114 of the tube 102. In a preferred embodiment, the inner diameter is generally constant from the first end 112 to the second end 114 of the tube 102.

Additionally, in one embodiment, the tube 102 has an angular transition 116 between the first end 112 and the second end 114 of the tube 102. In a preferred embodiment, the angular transition 116 provides for the second end 114 of the straw 100 to extend at an angle from the first end 112 for ease of use by the user. The angular transition 116 separates the tube 102 into a first portion 118 and a second portion 120. The first portion 118 of the tube 102 extends from the first end 112 of the tube 102 to the angular transition 116, and the second portion 120 of the tube 102 extends from the second end 114 of the tube 102 to the angular transition 116. Additionally, in a preferred embodiment, both the first portion 118 of the tube 102 and the second portion 120 of the tube 102 are generally linear. The angular transition 116, however, is generally not linear, but rather has a curved or angular portion, which may be referred to as an elbow in various embodiments. Because the angular transition 116 has an angular portion, the second portion 120 of the tube 102 extends at an angle with respect to the first portion 118 of the tube 102. In one embodiment, the second portion 120 of the tube 102 extends at an angle of between 20° and 40° to the first portion 118 of the tube 102. In an alternate embodiment, the second portion 120 of the tube 102 extends at approximately a 35° angle to the first portion 118 of the tube 102.

Referring to FIG. 3A, the distance between the inner surface 108 and the outer surface 106 of the tubular wall structure 104 is defined as the wall thickness of the tubular wall 104. Preferably, the wall thickness of the tubular wall structure 104 of the straw 100 is generally constant. In alternate embodiments, however, as shown in FIGS. 3A and 3B, the straw 100 has a plurality of annular grooves 130 in the outer surface 106 of the tubular wall structure 104 to reduce the wall thickness of the tubular wall 104 at each of the plurality of annular grooves 130. In such embodiments, except for the annular grooves 103, which have a reduced wall thickness, the wall thickness of the remainder of the tubular wall structure 104 is generally constant. In one embodiment, the annular grooves 130 have a flat 132 at a valley of the groove 130, and a radius 134 between the flat 132 and the outer surface 106 of the tubular wall structure 104. The annular grooves 130 provide bend areas to bend the straw 100 as shown in FIGS. 4 and 5 for storage in a container 140. In one embodiment, all of the plurality of annular grooves 130 are provided between the first end 112 of the tube 102 and the annular transition 116 of the straw 100. In one embodiment, as shown in FIG. 3A, the straw 100 has three annular grooves 130 to divide the straw 100 into four different sections as shown in FIGS. 4 and 5. As shown in FIG. 5, not all of the different sections of the straw 100 have an identical length. In a preferred embodiment, also as shown in FIG. 5, the different sections of the straw 100 can be folded approximately 180° at the annular grooves 130 so that they sections can lay adjacent other sections of the straw 102 when folded for storage in the container 140.

The embodiment(s) detailed hereinabove may be combined in full or in part, with any alternative embodiment(s) described.
